Exhaust leak from EGR tube
I've got an '89 Bronco with a 302 V8. There is a crack in the tube that runs from the exhaust pipe to the EGR valve, causing an exhaust leak. The crack is rather small, and is located under the intake manifold, about 6 inches from the EGR itself. Is there anything I can do to plug the hole short of replacing the tube? I thought of JB Weld, but I think the temp would be too great (above 500F). Any other thoughts? Also, how difficult would it be to replace that tube if it came down to it? Thanks.
